Title: Method and apparatus for control channel scheduling in a packet data communication system
Inventor: NGUYEN TRANG
IPC: H04W72/12
Filed: 2004-06-24
Granted: 2009-10-13
Abstract: A communication system (200) assigns a combination of values of multiple combinations of values to each of a first and second control channel parameter (for example, PSI1_ REPEAT_PERIOD and BS_ PBCCH_ BLKS). Based on the values assigned to the first and/or second control channel parameters, repeat periods associated with the first, second, and third control messages (P_ 1 and P_ 2, HR_1 and HR_2, and LR_1 to LR_7, respectively) are determined. New combinations of values of the multiple combinations of values are then assigned to the first and second control channel parameters and new first, second, and third control message repeat periods are determined in association with each combination. Optimal first, second, and third control message repeat periods are then selected from among the repeat periods determined with respect to each combination. Based on the selected repeat periods, an optimal combination of values is selected for each of the first and second control channel parameters.
